Improvement in stove-grates

IMPROVEMENT IN STOVE-GRATES.

Specification forming part of Letters Patent No. 121,363, dated November 28, 1871.

To all whom t may concern:

Be it known that I, THoMAs HARTLEY, of Bridgeport, in the county of Belmont and State of Ohio, have invented a certain new and useful Improvement in Fire-Grates and I do hereby Y declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawing forming part of the same, and in which- Figure l represents a vertical section of my grate applied to a fire-place; Fig. 2, a similar view thereof taken transversely. Fig. 3 is a plan view of the grate and a horizontal section of the fire-place walls, and Fig. 4, a view of the sliding scalloped frame or cover in an inverted position.

Similar letters of reference in the several figures refer to like parts.

This invention has reference to an improved fire-grate; and it consists of the gra-te itself when constructedin two parts, one of which being capable of lateral and longitudinal motion and adjustable upon the other 5 of the mode of supplying draught to the same, and of' certain other devices in connection therewith for the supply of air in small quantities and at a series of' points to the smoke in its passage from the grate to the flue of the chimney,I substantially as hereinafter more fully set forth and claimed.

To enable others to make and use my invention I will proceed to describe it.

In the annexed drawing, A refers to the fireplace. B B refer to the grate, which is constructed in two parts,the part B being held firmly in the walls of the fire-place A, while the projecting ends of the part B are made to enter elongated slots or recesses constructed therein, whereby it may have lateral movement, permitting of its being withdrawn a sufficient distance from the part B to allow of the contents of the grate to be precipitated into the nre-place below. To the stationary part B is fastened, or formed with it, a grooved projection or ledge, b, upon which rests and connects the movable part B to the said stationary part, so as to allow of the part Bl being readily detached from the same whenever occasion may require. O refers to a tube or pipe passing through the back wall of the re-place and entering au aperture in the back or stationary part of the grate, and which is for the purpose of communicating outside air to the fire in the grate. The grate-bar, whose upper end has the opening for the reception of the air or draught-tube C, is grooved, as plainly shown in Fig. l, from the said opening to the vertex of the grate, for the purpose of conducting the air or draught to the under side of the fire. D refers to an aperture at the lower terminus of the groove before described, and is for the purpose of allowing the air introduced into the grate by the tube O being carried off. Another aperture, d., is made in the upper rim of the movable part B of the grate for the reception of any suitable means for operating or agitating the grate when it is desired to remove ashes and the like therefrom. E refers to a sliding rim, the opening of which is of an oblong shape, and is for the purpose of permitting of the passage of the smoke om the grate on its way to the flue of the chimney. To make this rim removable it is constructed with end anges, which slide and fit within slots or recesses made in the side walls ofthe fire-place. F refers to another rim,

the lower edge of which is scalloped, and the horizontal portion thereof made to rest upon lugs or projections formed upon the sliding rim E, by which a space is formed between the two rims, allowing' the air to enter said space, from which it passes through the series of openings formed by` scalloping the rim F, and thence to the smoke arising from the grate. The object of so introducing the air or draught to the smoke is to cause it to readilyascend, or, as it were, be forced up the chimney. G refers to a folding-door, the lowest section of which is hinged to the outer edge of the sliding rim E, while the upper section thereof' has an opening to receive a projection fastened tc the upper front edge of' the fireplace for the purpose of retaining the said door up against the upper open portion of the fireplace when unfolded, but when folded up it is made to rest upon projecting bars fastened to or constructed with the said sliding rim.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-
